Replace the thermostat and re bleed system, do a cooling system pressure test to locate any external coolant leaks, ensure that you have a bleed pass thermostat fitted or just drill a 1/8" hole in the flange of the thermostat so this can help the system bleed out air, it wont affect the temp of the system.
